z-wave
what networks are used by many popular wireless internet of things network protocols like Zigbee and z-wave for device communication, use less power than other wireless connectivity options, and is a decentralized network of connected wireless axis points also called nodes?
Wireless Mesh Network, WMN
what do you call it when a network can recover on its own when a node fails?
the network is self healing
what does each wireless access point node in wireless mesh network due until the data reaches its destination?
each node forwards data to the next node
what do good nodes do to data to exclude a failed node?
reroute
